Application filed November 11, 1914. Serial No. 871,606.

0 all whom it may concern:

Be it known that I, WYATT M. INsKo, a citizen of the United States, residing at Oarlisle, in the county of Nicholas and State of Kentucky, have invented certain new and useful Improvements in Grain-Doors; and I do hereby declare the following to be a full, clear, and exact description of the in vention, such as will enable others skilled in the artto which itappertains to make and use the same.

My invention relates to grain doors and comprehends certain new and useful improvements ingrain doors for railwaycars of the type that are removable and comprise a number of hingedly connected door sections which may be folded.

The primary object of my invention is to provide a removable sectional grain :door for railway cars that is provided with effect ve outlet means including a flexible and extensible discharge spout so arranged that the contents of the car may be discharged therethrough without necessitating removal of the door.

Another object is to provide a car door which consists of upper and lower sections that are hingedly connected with each other at a point near the center of the door, the upper section comprising a pair of hinged portions, the upper being arranged to swing inwardly so that when desired a person may get into the car without necessitating the removal of the entire door.

Another object is to generally improve grain car doors so as to render them more practical, reliable and efficient in operation and capable of being assembled and disassembled without materially increasing the cost of manufacture thereof.

The above and additional objects are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification and then more particularly pointed outin the claim.

With reference to. the drawings, wherein I have illustrated the preferred embodiment of my invention as it is reduced to practice, and throughout the several views of which similar reference numerals designate corresponding parts- Figure 1 is a fragmentary side elevation of a grain car showing my door attached and in closed position,

.5 Fig. 2 is an inside elevation of the door,

Fig. 3 is a vertical sectional view taken comprises lower and upper door sections 1' and 2 respectively that are hingedly connected with each other by specially constructed hinges 3 which are mounted upon the outer faces of the sections 1 and 2. Each of the hinges 3 comprises leaves 4 and 5. Rolled ears are-carried upon the opposed ends of the leaves 4 and 5, said opposed ends being disposed in spaced relation to the meeting edges of the sections.

7 A link member 6 having ears on its end connects the leaves 4 and 5 with one another. Hinge pins 7 are inserted through the ears on the members 4, 5, and 6, said ears alining. It will thus be seen when the sections 1 and 2 are folded, they are held spaced apart for a distance, equal approximately to the length of the link member 6. This arrangement is for a purpose to be later more fully described.

The upper section 2 comprises upper and lower sections 8 and 9 respectively of the same size and which are hingedly connected with each other by suitablehinges 10 which are arranged upon the inner faces of the sections 8 and 9 so as topermit the upper section 8 to fold or swing inwardly relative to the car.

As a means for holding the upper section 8 or in fact the door securely within the frame, I provide an L-shaped bracket 11 to be secured upon the lower face of the upper horizontal bar 12 of the door frame A and having its one arm portion depending from said bar 12 and apertured to receive a bolt 13 carried by the upper section 8. The bolt 13 is inserted through said member 11 and a 11111; 14 is turned on the threaded end of the I provide means for holding the sections 8 and 9 of the upper section 2 in comparatively rigid relation to one another which consists of a locking metallic strap 15 that is hinged as zit-16 to -the lower 'section 9 of the up-persection 2 and arranged to extend upwardly and engage the outer face of the upper section 8. The free end of the strap 15 is longitudinally slotted to receive a bolt 16' inserted from the'inside ofthe upper 3 section 8 and having a nut 17 turned on its outer or threaded end. It will be seen that when the "bolt 16 is inserted through the slotted end of the strap and the nut 17 turned to clampthe strap upon the outer face of the upper section 8, a comparatively rigid structure isprovided.

Fixed upon the inner faces of the sections 1 and 9 are back strips 18 which are apertured and arranged to aline with apertures in thesections 1 and 9. Bolts 19 are car-' ried by thevertical bars of the door frantic A and have their threaded ends disposed beyond the outer facesof the bars of the In the frame A to which they are attachedso that they maybe inserted throughthe apertures in the sections 1 and 9 and back strips 18 as shown in Fig. 3 in the drawings. Nuts 20 are turned on the outer ends of the bolts 19 andsecurely hold the door B in position. To remove the door Has an entirety it is first necessary to remove the nut 14 attached to the upper section S from the bracket 11 and to remove the nut 20 from the bolt 19. When the door sections are folded as shown in Fig. 4 the back strips 18 are removed. Carried adjacent to the lower edge of said section 1 are bolts. 21 which have their threaded ends disposed. outwardly from the outer face of the section 1 and have mounted on said extended portions cylindrical spacing collars 22. The bolts 21 extend beyond the outer ends of the collars 22 sufficiently to be inserted through openings 23 formed in the upper section 2. This arrangement is hadwhen the door is folded as shown in Fig. 4 Nuts 24 are turned on said bolts 21 after they are inserted through the apertures 23 as described. 7 Thus it will be obvious that the door willbe locked in folded position. v a

lower door section 1 at a point adjacent to its lower edge, I provide an outlet opening25. Secured to the lower door section 1 and communicating with the discharge opening 25 is a flexible'and extensibledischarge spout 26 which isarranged to be disposed in an outwardly and downwardly curved position. This discharge spout 26 consists of aplurality of telescoping frustoconical'rings-27, the innermost and smaller 28 of which being secured to a flat metal body or attaching plate 29 and alining with the opening formed in said plate. 29.1 V

Secured upon the outer face ofthe lower door section 1 is a base plate 30 having a 'circularopening 31' therein which alines'or communicates with the opening 25. Rotatablymounted between the'plates 29 and 30 is a disk valve, 3,1 provided with an open therefor isprevented.

ing "32 thereinarranged to aline with the opening in the plate 29 and the one 31. A

bolt33 is inserted through thedoor section .1, plate 30, aperture 34: in the center of the disk valve 31 and plate 29. A nut 35 is turned upon the outer end of saidbolt 33.

'The detaching plate-29 is provided adjacent to its upper edge withan arcuate slot 36. An operating disk valve 31 adjacent to: the' perlphery thereof and upon its forward face and is slidably mounted within the slot 36. By means of the handle 37 the disk valve 31 ma'y be'rotated to bring the opening 32 into and out of registration with the discharge opening 25 and opening 31in the plate 30. As a means for locking the diskvalve' 30 in such position that the opening 32 will be out of registration with the opening 31 in the plate 30, I provide a locking plate 38 that is hinged as at 39 to the plate 29 at one end and at its other end is bifurcated as at 40 m recelve thehandle 37 The plates 29 and 30..are secured by bolts 11 that are inserted through the section 1 and the plates 29 and 30 adjacent to theedges of the plates so as not to interfere with the disk valve'31" upon rotation. of said valve.
